Answer:
7
Step-by-step explanation:
4x+12-2x=26
Or, 2x=26-12
Or, 2x=14
Or, x=7
Answer:
Yes, I can help what do you need???
Step-by-step explanation:
The graph is a function of x because the line x = 5 does not intersect the graph.
The graph is not a function of x because the line y = 0 intersects the graph at two points.
The graph is a function of x because the line y = 5 does not intersect the graph.

Answer:
Change produced in cone is greater than change produced in cylinder.
Step-by-step explanation:
Given : A cylinder and a cone start with the same radius and height.
We have to find which change produces a greater increase in volume.
We know Volume of cylinder =
and Volume of cone =
Where r is radius and h is height.
Let r' and h' denotes new radius and new height
Consider Cylinder first ,
The radius of the cylinder stays the same, but the height of the cylinder is doubled.
that is r' = r and h' = 2h
Then Volume of new cylinder becomes,
Volume of cylinder =
that is
Now, Consider Cone, we have,
The radius of the cone is then tripled, and the height of the cone is cut in half.
r' = 3r and h' =
Thus, The volume of new cone becomes,
Volume of cone =
that is
Thus, Change produced in cone is greater than change produced in cylinder.
No, the lengths 3, 4, and 9 cannot form the sides of a triangle.
The triangle inequality is a fundamental geometric principle that states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
We have sides as 3, 4 and 9.
For a triangle to be valid, the sum of the lengths of any two sides must be greater than the length of the third side.
In this case, let's check if this condition is satisfied:
3 + 4 = 7
7 is less than 9
Therefore, these lengths do not satisfy the triangle inequality theorem, and a triangle cannot be formed with side lengths 3, 4, and 9.
